i will look around to see if it possible to get it somewhere in europe before i buy the one from US
what does the heatsink do? does it just cool it better like a heatsink normally does? or does it have some other use in wc

Watercoolinguk.co.uk has the 3.2, A couple of these would be ideal. If you're going with the 35x, make sure they have some air flow.

That's not true. All DDC3's put out heat, not just the 35x. The 35x actually puts out less heat because of it's PWM in daily idle use where as a regular DDC3 will be running 100% all the time unmodified.
And as far as the heat goes, the heat is outside the loop and not into the loop, just the way I like it. Also, I doubt he will have air flow issues, look at the man's case! Getting some heatsinks or just putting some on according to Martin's heatscope article will work too.

We discussed on the water thread quite a few times (didn't see you in either discussion), the 3.25 is a bit more hot than the 3.2 that's why I don't recommend it. Most ppl wont use pwm on the pump tbh. Other than that, since he's got a pedestal, go for a couple of tricked out D5 or the tried and true 3.2. With the money you save versus the 3.25, get a dual top to connect either the two ddc(s) or d5(s).

They all get hot lol. The heatsink isn't needed if you have decent flow. I use heatsinks cuz 35 bucks is nothing to me times two. And I'm of the mindset that hell I've already gone that far, what's a lil bling bling on my pump that no one will see, and if yer noticing you'll see the bottom 140mm fan right under the pumps.

If you feel different, than that is your judgement based on your experience. I'm absorbing what others have said from their experience. Like I said, the 35x will be hotter based on what I've told by other owners on the water thread. Any DDC really gets hot in confined places like a bay/pump/res (discussed as well), and really, why would you want pwm on pump unless you're trying to control its power to mediate its heat, ? Both my DDc 3.2 and D5 will get a bit hot in a bay/res. Out in the open, they're fine. So again, why pay a lot more for slightly more performance, pwm which most likely op will never use, and more heat?
The 3.2 is great pump, so is the D5 (a little bit noisier for my taste). I don't see the added benefit in the higher cost of the 3.25.
I recommend what I know works and what I've been told works. If someone said their 3.25 farts magic fairies, that's fine. But based on the info I accumulate by partaking in the water cooling thread, I put that use. I know there are those who know a lot more than me and when they prove me wrong, I welcome the knowledge.
And honestly, lets both try to keep it more conventional for op. I don't want him ending up with parts that he will have reservations about in the future.
